|Last Chance Grade on US 101 in Del Norte County.|
The slide activity is a serious concern because there’s no viable alternative route in the event of a complete failure of the roadway due to a landslide. Without a detour, residents could be cut off from medical care, schools and other important services, and the economic impacts would be devastating.
A new highway alignment will be constructed eventually that will offer a permanent solution to instability and potential roadway failure. In the meantime, the department has begun using a new, advanced, and multi-faceted system to monitor landslide activity at Last Chance Grade. Check out the video below to see how this sophisticated system works.
